Detectives have questioned a man over the dissident republican murder of a father-of-four.
Kevin Kearney was gunned down as he walked his two dogs through Alexandra Park in north Belfast last October. His body was found floating in a lake in the park a day later.
Detectives from the PSNI's Serious Crime Branch investigating the killing arrested a 32-year-old man in the Docks area of Belfast yesterday morning.
He was taken to Antrim Serious Crime Suite for questioning and remained there last night.
Mr Kearney (46), from Dunmore Avenue, was known to police for previous offending and officers are exploring a possible drugs link to the killing.
The murder was claimed by a group styling itself as the IRA.
